IMPROVEMENT IN WIND MILLS.

Specification forming part of Letters Patent No. 175,814, dated April 4,1876; application filed March 18,1876.

To all whom it may concern:

Be it known that I, JOHN ZIMMERMAN, of Earlville, in the county of LaSalle and State of Illinois, have invented a new and valuableImprovement in Windmills; and I do hereby declare that the following isa full, clear, and exact description of the construction and operationof the same, reference being had to the annexed drawings, making a partof this specification, and to the letters and figures of ref erencemarked thereon.

The figure of the drawing represents a vertical sectional view of mywindmill.

My invention relates to windmills for pumping water; and it consists inthe construction and arrangement 01' devices for automatically startingand stopping the wheel, as will be hereinafter more fully set forth.

In the annexed drawing, A represents a wellcover, with trough B arrangedthereon for receiving the water drawn from the well by the pump 0. Thispump is constructed in any ordinary manner, and its plungenrod Dconnected to the horizontal crank-shaft, which is arranged in bearingsupon a turn=table, H, on

top of the tower G, said shaft having upon end the wind-wheel J. Theblades or fans of the wheel are connected, by suitable rods and levers,with a sliding collar, a, on the shaft, and this collar, by rods b, withtwo L-shaped levers, I, which, in turn, are, by rods d, connected with arotating disk, It, within a lever, M, so arranged that the disk can turnfreely therein and yet be raised and lowered by the raising and loweringof the lever, and thus throw the fans of the wheel in and out of gear.From the end of the lever M is suspended a weight, N, balanced bymeans.of a bucket, O, hanging from the end of a rope or chain, k,

which passes up through the well-cover over a pulley, t, and is attachedto said lever. In the bottom of the bucket 0 is a valve, a, which isoperated to let out its contents by means of a rope, 0, passing upthrough the well-cover A and attached to one end of a lever, P, pivotedto a standard on the'edge of the trough B. The other end of the lever Pis, by means of a rod, 7', connected to a float, S, in the trough. Tothe same end of the lever P as the cord 0 is attached another cord, .9,which passes upward over the pulley t and downward through thewell-cover, and is attached to the valve of a faucet, Q, in the pumpstock.

When the wheel is in motion the water is pumped into the trough B, andthe float S rises with the water. This depresses the outer end of thelever P, which, by the cord 8, opens the faucet Q and allows the waterto flow into the bucket 0. When this bucket is full it overbalances theweight N and raises the lever M, thereby throwing the wheel out of thewind and stopping the motion of the pump. As the water is drawn ofl'from the trough B the float S descends, raising the outer end of thelever P. 'This closes the faucet Q and opens the valve n in the bottomof the bucket 0, when the contents of the bucket will flow out, allowingthe weight N to depress the lever M and throw the wheel in the windagain, and thus again set the pump in motion.

It will thus be seen that the wheel is automatically thrown in and outof the wind to start and stop the pump, according to the state of thewater in the trough B.

If a continuous supply of water is required, the valve or spigot of thetrough is to be left open, so that the float S will always be down, andthereby holding the wheel in the wind.

What I claim as new, and desire to secure by Letters Patent, is-- Incombination with the weighted lever M, arranged to operate upon awind-wheel for throwing the same in and out of the wind, the float S,lever P, cord 8, faucet Q, bucket O,

with valve 12 and, cords 7c 0, all arranged to' operate substantially inthe manner and for the purposes herein set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JOHN ZIMMERMAN.
